To all '1v/"10m it may concern:

lie it known that I, Roms PniicivAL LINK, a subject of the King ot Great Britain, re siding at llfinchmore Hill, hliddlesex, England, have invented a. new' and useful iiiqiiid-Dispensing Machine, of which the 'following is a specification.

This invention Yrelates to an improved refreshment fountain or like liquid measuring and deliveringmacliine for supplying dif feiently flavored drinks.

The improved machine comprises a mixingl vessel, a number of vessels each supplying a differently flavored Havering material and mechanism by means of which, after a; preliininary setting to establish communication between the mixing vessel and a selected vessel supplying tlavoring material, on turning a handle, a supply of rinsing ivater is tirst delivered into the mixing vessel and then drained away, after which a measured.

quantity ot tlavoring material, unaerated water, and a further quantity of water with which an aerating gas has been previously mixed in ay separate chamber, are delivered into and mixed in said vessel from which the drink thus prepared can then be drawn etti tachedgtrom the .neclianical operating de` ofi.

As shown, the machine comprises a casing in which ils mounted a rotatable shaft 2, having an operating handle 3 mounted Fig'. 7 shows i Ti. l? ll and l2 are detail vievvshere thereon. crank-arm l and link 5 (Figs. 3 and 7 to a draw bar 6 slidably mounted in guides 47.

A,The draw bar and shaft are-locked against movement by a. stop S (Figs. 4 and 7) en countering an abutment bar 9 pivoted at 10 and carrying a coiinter-Weight 11. On introducingfa coin 1Q through a coin passage' 13 into a coin cup comprising pivoted members i4, let the abutment bar Q is'loWered to the position shown in Figl setting free the stop 8. By turning the shaft i2 1n the direction indicated by the arrow F ig. 7, the draw bar G is moved to the left carrying a coin ejector across the coinavliich is thus pushed through between the members 14 which yield and. release'the coin so that the abutmentbar is raised by the Weight `11 when the draw bar-returns to its initial position as hereinafter described. In the guides 7 there is also mounted e. dash-pot bar 16 connehted to a piston 17 Working in a cylinder 18 filled with a liquid which `is forced from end to end of the cylinder9 by the movements of the piston 17,k through' a conduit 19 controlled by an adjustable valve 2G to regulate the speedl of movement o the said bar 16 which is also connected to the .draw'bar 6 by a cord 2l Wound on a spring- `actiated roller 22 arranged to Wind upthe voor As the draw barl inoveto the left, Fig.' v7, a cam surface 23 thereon forces a spring controlled nin 2li into a' notch 24 in the dash-pot bar lo and thus locks the latter to.

pause in the movement of the bar 6 until a4 cam surface 25) on thebar' l@ movesover 'and releases the latch 26, this action taking place during the movement of bar 16 to the left. l/Vhen the latch '.26 is 4disengaged ,from the slots 27 .the bai-.6. can be returned to its iniiiV tial position by. rotating theshaft 2 in the opposite direction to thatindicated by the arrow in Fig. '7, and is locked at the end of its'stroke'by the lugs 25 entering slots 33 in guides 7. The bar 16 which has previously been locked in place during the return movement ofbar 6 by the pin 24 being raised into a notch 24?, due to the passage of cam 23 therebeneath, is released when the notch at the front end of said cam is reached and follows the bar 6 being drawn along by the cord this rinsing water to drainv away through the 21 and restrained by the piston 17. The draw bar 6 is prevented from reversing its direction of motion until it has completed its stroke in either direction by a swinging pawl 34 and a'rack 35 fixed to the casing 1. As the bar,6 moves to the left a tappet 36 thereon moves a spring-pressed valve con trolling lever ,37 (Figs. 2l and 5) and opens a valve`38 so that water from a main supply pipe 39 passes throu h a pipe 40 (Figs. 1, 2 and 13) ,and issues through distributing ori- -fices 41 intoy the interior'fof a mixing vessel 42 to rinse the same. A cam plate 43 whichv is connected to bar 6, as shown in Fig. 8, for movement therewith, is carried forward with said barv so as to engage and raise a Valve rod 44 and thereby open a valve 45 to allow conduits 46. The lever 37 .when moved as i .above described is retained in this position by a latch 47 after the tappet 36 has passed the end'of the'said lever. As the rod 44 rises, a spring pressed bar 48 enters a notch 49 therein to hold the valve 45 open.A

The lever 37 is coupled by a. link 50 to a llever 51 which opens a valve 52 :allowing water to pass through a pipe 53 to a beater chamber 54. 'One end of the lever 51 engages an inclined vslot between bars 55 fixed on a rod 56 (Figs. 3, 11 and 13) which is thereby moved to open a relief valve 57 to permit escapeof air or gas from the chamber 54.

- The'lever 37 is also coupled by a rod 58 to a spring-pressed valve lever 59 which -admits water through a valve 60 and conduit 61 to a.

spraying device. 62, to rinse a vessel 63the bottom of which opens into the mixing ves-l sel 42. ,I

In addition Yto the tappet 36, the draw bar 6 is provided with a pair of pivoted tap- 'pas e4 and ce, (Figs. 5' and e), thtppet,

64 being controlled bya spring 65 and being located to the rear of the lever 59, `while the tappet 66 is located in front of' a spring-- in the position shown in Fig. 5 by a latch 68,

Fi s. 2,- 5 and 13), while the tappet 64 strikes against the lower end of lever 59 and rocks idly past the same. There is also a still further tappet70 on bar 6 which de` pends therefrom, and, during the above speci'ed F'movement of saidbar, strikes against and idly rocks to the left a sprinaf`4 controlled pivotallyT mounted member i l constituting an extension of bar 48. The above-mentioned lever 67 controls a valve 69, (Fig. 13), which remains closed during the time that said lever occupies the position represented in Fig. 5.

By rotating the shaft 2 in the direction indica'ted by the arrow (Fig. 7) a pin 72 (Fig. 10), on a gear Wheel 7 3 is brought against an arnr74 pivoted at its upper end to casing 1 and raises the said arm until the outer ond of aspring-controlled latch 75 thereon passes above a plate 76, against which it is caused to strike during the upward movement of the arm, thus hlding tie arm raised. Arm

74 is connected by a link 7 7 and arm 78 with a valve 79 in a conduit 80 leading from the beater chamber 54 to the mixing vessel 42, this valve being closed by said parts 77 and 78 when said armis raised.

The valves 38, 45, 52, 57 and 60 remain open after the bar 6 has completed its move.- ment to the left, during a period determined by the rate of travel of the bar 16 after the latter has been released by the pin. 24,k until a lug 81 thereon releases the catch 47, where upon lever 37 is returned by the action of its controlling spring and, owing to its connection with levers 51 and 59, brings about their return also, so that the valves 38, 52, 57 and 60 close. As a result of the movements described, the vessels 42 and 63 ha've been rinsed and drained, and the beater chamber 54 has been charged with water. The drain ing valve 45 remains open. During further Vmovement ofthe bar 16,'a lug 82 thereon withdraws the latch 68 from the lever 67 which is turned by its spring 83 and opens the gas valve 69 so that compressed gas passes from a suitable source of supply through a pipe 84 to the pipe 53, and thence to thebeater chamber 54. The bars6 and 16 having both arrived at the left hand ends or their respective paths of travel, the bar 6 is unlocked by the cam 29 depressing the latch 26- and both bars can be returned to their initial positions by turning the shaft 2 in the opposite direction to that indicated by the arrow in Fig. 7.

The shaft 2 is made in two parts connected by 'a clutch com rising a pivoted latch 30 on one .part presse by a spring into a notch 31 in the other part (Figs. 2, 3 and 10). As the shaft 2 rotates, carrylng thebar 6 toward the right (Fig. Y), the end 30a of the latch 30 engages the tri 32 and is depressed thereby so that the en 301 is disengaged from the notch 31 leaving the part of the shaft remote from the handle 3, at rest. The rotation of the handle 3 in this direction, with the adj acent part of the shaft carrying the gear 73, can then continue until after the latch end 30, which is then held toward the axis ofthe shaft by the end 30b traveling on thel surface sol amene of the part of the shaft which is at rest, has

passed under the spring-pressed trip arm 32,- and until the end 30b drops into the notch 31 'whereupon the shaft is locked bothl by the latch 80, and by the engagement of stop 8 with bar 9, until ,another coin is inserted.

When the vhandle 3 is turned a pinion 114' meshing with the gear 73, rotates a beater in the chamber 54 so thatif 'this chamber containsr charges of Water and an aerating gas the solution of the gas in the Water is accelerated. The latch 80 allows the handle 3 to be turned as hereinabove described through a distance greater than that necessary to move the bar 6^. through its full stroke, in order that a sullicient action ol the beater can be obtained.

As shown in Figs. 1, 2 and 3, a number of' measuring chambers 85 are provided each communicating through a corresponding pipe 86 with a diderent reservoir 87 (Fig. 12) 'containing Havering material. Each chamber 85contains a lioat valve88 and is open at its upper end through a socket 89. A cylinder 90 (Figs. 1 andlel) mounted on trunnions"91 in a .frame 92 movable on guide 93, has a nozzle 94 which moves over the sockets 89 during the travel of the said cyl inder and its frame, such travel being` due to the provision of a connection 05 between said frame and .a shaft. 90, the latter having a handle, 97 exterior to the casing land moving over a suitably marked dial 98. 'lhus'the nozzle can be brought above a selected meas# uring chamberbefore the 4mechanism controlled by the handle 8 is set in operation. When the shaft 2 is turned, a cam-90 thereon tilts the cylinder 90 so that the nozzle is pressed into the socket 89 directly below it. A crank arm 100 (Fig. '1) the eil'ective length of which can be varied, is connected by a rod 101 to a piston 102 in the cylinder 90, by means of which piston air is Withdrawn from the chamber 85 in order to draw Havering material by suction into said cham ber through pipe 8G until the float valve 88 reaches the top of the chamber. A. loaded valve 108 then opens to admit additional-air,

and also to prevent excessive suction andl consequent leakage at the valve 88. rllhe/la vering material is drawn in through a check valve 101 (Fig. 12). When the piston 102 is moved inthe opposite direction the air eX- pelled from the cylinder 90 forces 'lavoring material out oi the `chamber 85 and past a check valve 105 through a pipe 10G into the vessel G3. Another check valve 107 (Fig. l) is provided in the pipe 10b thevalves 105 and 107 acting to keep the pipe 106 charged so that a definite quantity of Havering Ina-y terial is expelled at each actuation of the piston 102, the chamber 85 being closed by the valve 88 when empty.

Alinement or the nozzle 94'vvith any selected socket. 89 is insured. by a spring pin 108 (Fig. 1) entering one of the notches 109 ina bar 110 supporting the sockets 89. A plate 111 is secured to frame 921er Inovethrough a slot inA this plate and is, in consequence, shifted laterally by said plate along shaft 2 in accordance with the movements of said frame. Plate 111 has a spring connection 112 with the cylinder arm 113, whereby said arm is held against the periphery. of cam 99. During the foi-Ward or lefthand movement of bar 6, the tappet rocks the pivot member 71 idly, Without producing any movement of bar 48, but when said bar' 6 makes its return :movement and the tappet again engages member 71, it Will press the latter against a shoulder on bar 48, and in consequence will rock the said bar 18 counter-cloclcwise, I gaging it from note [19 in the valve rod 114, whereupon said rod will drop and close valve 45. The crank arm 100 commences to move the piston 102 to eject the tlavoring material into the vessel 63 as labove mentioned. The tappet 64- t-hen opens the valve G0 a slot 117 in the rod 58 permitting this to be done without moving the levers 37 and 51. The valve 60 is in this instance locked by the latch .116 (Figs. 2 and 13) but this valve is not so locked when moved by the rod 58. When. the valve G0 opens Water is supplied to the spraying nozzle 62 to Wash the tlavoring material into the vessel L12. This Water, together with aerated Water from the chamber 511 lifts a float valve 118 which closes the vessel 42 When filled to the proper eX- Vtent. The aerated vvater just referredl to, is supplied to vessel 42 consequent upon the opening of the valve 79 produced by the dis engagement of latch 7 5 from plate 76 and the subsequentdoivnivard movement of arm 7&1, the release of said latch being elected by the engagement, during` the rotation of 4gear 78, of pin 72 with a trigger 7 5 to which theinner end of the latch is pivoted, 'Whereby it is retracted until. its outer end is Withdrawn from said plate. Un further move ment of the bar 6 the tappet 60 closes the valve 69 which becomes locked by the latch ,68, and nally thebar 16 following the bar 6 closes the valve 60 by a lug 119 releasing the latch 116. The chamber 42 is now charged vvith flavored aerated Water, the 'valves 45and 118 are closed, and by opening the valve 120 by means of the handle 121, the beverage is expelled through the pipe 122 by the pressure of the gas escaping from the Watr,`this pressure holdingthe valve 118 closed until the vessel` 42 is emptied. The parts are new in their initial positions ready to repeat the cycle of operations hereinabove described.

To receive the beverage discharged from pipe 122, there isV provided a cup 123 which is attached-to the machine and normally Fig. 2),- thereby disen-v -ment therewith, and the cam 99 Works gse ' rests in a recess 124 into-which it is drawn by a ord 125 wound up by a spring roller. 126. Vhen the cup is removed a part 127 of the bottom wall of the recess is raised by` a spring 128 and moves a ewl 129 into engagemcnt with a ratchet w eel 130 restrainmg the roller 126 from winding up the cord. lWhen the draw bar 6moves to the left, a,

projection 131 (Figs. 8- and 9) thereon.

10 enters an openingin the rear wall of the recess and thrusts the cup va short distance outward so that it vmay be readily grasped. ,When the cupY is left'free hanging by thecord 125 the latterdepresses the part 127 M so that the ratchet is releasedY and the cup drawn back into the recess.

To rinse the cup, it is pressed downward upon a perforatedplate 132 e uipped with .a depending rod 134, (Fig. 4 lthe lower'- end of which is .normallyfenwaged by a t detent 133 provided upon the baisance weight 11.l -The rocking of this weight, effected previously in connection with the introduction of "the coin necessary to operate thevr machine, serves to release the detent from free to descend under the pressure imposed thereupon, against the action of a spring 135, (Fig. 1), thereby, opening a valve 136,

rose nozzle 138, whence it is discharged, washes the cup, and escapes through the perforations in plate 132 to the drainv pipe 46.

The operation, as a whole, is substantially as follows z-The handle 97 is first. moved in the proper direction to bring the pump cylinder 90 into position for coperation withthe chamber 85`corresponding to the liavoring extract selected, the movement of the cylinder being produced by means of the connect-ion 95 of its frame 92 with the shaft 96 and resulting in the disposition of its nozzle 94 directly above the socket 89 ofthe selected chamber. A coin is then inserted in the passage or chute 1,3 and falls therefrom into the cup 14 provided ,in the abutment bar 9, the weight of the coin depressing said bar suiiiciently to disengage it from the stop 8 on the front cud of the draw-bar 6 and, at the same time, to disengage detent 133 on weight 11 .from the end of the cup rod 134, so that both the drawbar and the cup are unlocked. The handle 3 is next grasped and pulled forward, z'. c., 'in the direction of 'the arrow in Fig. 7. y.which action produces, initially, a partial rotation of shaft 2, and a consequent movement of bar 6 in the same direction through the agency of' the parts 4 and 5, said bar being at that time free to move, since its latch 26 is depressed by` the cam 29 on bar 16 and thus disengaged from slots 33. As

the rod end, and the rod and plate are thus-A lvVater then dows through pipe 137 to a .'47 from lever 37, whereupon that lever und soon ae bar @starts to move lforward, pin 24v vis raisedout of the seat at the front endV` `matically returned to normalA posif'i. ;ci,

of cam 23 and caused to enga-ge notch 24'L in bar 16, thereby locking the latter against beneath pin 24, whereupon the pin will be lowered by its controlling spring land thus release bar 16, .such action taking place at thel end of the forward movement of bar 6. Prior to. this release, however, the lejector movement until -the rear seat 28 is brought 15 on the front end of bar 6 engages the coin and pushes it downward through the cup. Bar 6 continues its forward movement until stopped by the engagement of latch 26 with slots 27, and during such move-4 'ment its tappet 36 actuates lever 37 and,

also, through the agency of .the parts 50 and '58, the levers'51 and 59, thereby opening the valves 38, 52, 57 and 60, with'the result that water from' the main sup ly pipe 39 Hows through pipe 40 into the Jnried by bar 6, with the lower endof the valve rod'44, and isheld insuch position by the engagementof bar'48 in notch 49 in said rod end, so that the 'water used for washing vessels 42 and 63 is drained off continuously during the washing operation. During the initial, or forward movement of shaft 2, the piston 102 of the previously adjusted pumpl is'drawnout-wardly of the pump cylinder 90 by the action of crank arm 109, but slightly before .this stroke commences, the cam 99 acts oncylinder arm 113 and rocks the cylinder about its trunnious 91, so that. the nozzle end of the cylinder is depressed and forced into the socket 89 of the measuring chamber 85 therebeneath, making a tight joint with said socket.'

When the piston moves outward, it will then exhaust the air from the measuring and draw the lavoring extract yinto said by valve 88 seating in the upper, e'nd of the chamber. Valve 103 in the pump cylinder then opens, to prevent over-suction and lealtage. About the time that piston 102 ,coniplctes its outstroke, the forward movement of bar 6 is terminated bythe engagement of latch 26 with slots 27, such engagement, being practically coincident with the release of bar 16 by pin 24 due to thelatter dropping into seat 28. 4The forward movement of bar`16 then commences by reason of the pull exerted upon said bar by cord 21, and during this movement lug 81 releases latch j al,
